DETAILED DESCRIPTION OF THE INVENTION

In the preferred embodiment illustrated, there is provided a mobilephone having an internal printer which includes a separately detachableprinthead and ink supply module. The printer phone can be produced at orclose to a standard size phone for any system including PHS, GSM andGPRS, thereby conferring a higher level of convenience during operation.

Turning initially to FIG. 1, there is illustrated the preferredembodiment 1 in the form of a PHS phone and which in many ways lookslike and includes the features of a conventional mobile phone of thistype including an ear piece 2, microphone 3, aerial 4, loud speaker 5, aseries of push buttons 6 and a preferably color LCD screen 7 for thedisplay of information. Also included is a battery 8 as shown in FIG. 4.

The phone 1 can optionally be equipped with a camera device 10comprising lenses 11 and associated CCD chip or CMOS sensor 12. The CCDor CMOS sensor enables the device to store images on demand, so that thephone can effectively act as a camera device for the printing out ofimages, or for their capture and forwarding across a mobile phonenetwork. The operation of the relevant part of the internal controlelectronics can be substantially as set out in the applicant's earlierPCT application WO 99/04551 entitled “A replenishable one time usecamera system” the contents of which are incorporated herein byreference. In other embodiments, the camera device may also beconfigured to enable video conferencing by facilitating simultaneousimage-processing during phone transmission. A camera function that ismounted for selective movable positioning on the phone device may beuseful for this purpose. For example, it may be rotatable between aforward facing camera orientation and a rearward facing videoconferencing orientation.

The printer apparatus is shown generally at 15 and comprises a printheadand ink supply module 16 including a printhead 17, an inksupply/distribution unit 18 and a print media feed apparatus 20. Thefeed apparatus is of a conventional form including a motor 21 withassociated gear train 22 which drive a series of feed rollers 23.

The packaging of the printer apparatus 15 is best shown in FIGS. 5, 6and 9. In this regard the printer phone 1 is constructed around a rigidchassis molding 25. The chassis is adapted to slideably receive andretain the printhead and ink supply module 16 by means of retainingflanges 26 provided on the outer casing of the printhead and ink supplymodule 16 which cooperate with under cut channels 27 provided on thechassis molding.

The full operation of the printer apparatus 15 is best illustrated inFIG. 9. In use print media 30, preferably in the form of business cardsized paper or card sheets, is fed in through an entry slot 31 providedin the external phone casing 32. This can be done manually or via adispenser as described hereafter. The card 30 is then picked up by thepowered entry feed rollers 23 and delivered to the printhead and inksupply module 16. The printhead and ink supply module 16 can besubstantially the same as that disclosed in Australian ProvisionalPatent No. PP6534 filed 16 Oct. 1998 (U.S. Ser. No. 09/425,419 filed 19Oct. 1999), the contents of which are also hereby incorporated bycross-reference. In such a device, the printhead is in the form of anelongate printhead chip that extends the full length of the print mediapathway, so as to print the full width of the print media in a singlepass without the need for any printhead traversing mechanisms.

In this particular preferred embodiment, the printhead and ink module isformed as a sealed unit which is replaced in its totality after apredetermined amount of usage. The detailed structure of the ink supplyand printhead module is shown more clearly in FIG. 8. The inksupply/distribution unit 18 is of a molded multi-part structureincluding a cover 35, a macro channel molding 36 defining four separateink supply chambers 37-40 having therein optional flow control baffles41. Connected with converging outlets of the macro channel molding 36 isa micro-molding 42 which defines similarly converging ink flow nozzles43 that accurately direct the ink to minute ink supply inlets on therear of the printhead 17. Optionally, an ink filter 44 is providedbetween the two moldings. A capping device 47 is also provided as partof the module for sealing and protecting the nozzle outlets when theprinter head is not in use. It is estimated that the ink supply will onaverage be sufficient for printing approximately 1000 pages at 15%coverage of black or 100 photos of 50% coverage of CMYK. An expandedtechnical description of the printhead and ink supply module can befound in the aforementioned provisional patent specification PP6534 andassociated applications.

The mobile phone system can be operated under the control of a series ofone or more application specific integrated circuits (ASICS) whichincorporate the usual mobile phone capabilities in addition to cameraand image processing capabilities. An adaptation of the system outlinedin PCT Patent Application PCT/AU98/00544 filed by the present applicant(also incorporated herein by reference) can be utilised in the design ofthe ASIC. The electrical interconnections for the preferred embodimentare shown schematically as a block diagram in FIG. 16. Other systemdesigns well known to those skilled in this field may also be used.

Referring next to FIGS. 11 to 15 there is illustrated a print mediadispenser 50 configured for use with the PHS phone of the previousembodiments. The dispenser comprises a lower molding 51 that defines amedia storage and dispensing region 52 and a cradle 53 which supportsthe printer phone 1 and aligns it with the outlet of the dispenser.

The interactive operation of the print media dispenser with the phone 1is best illustrated in FIG. 14. As can be seen, the dispenser 50 has astorage area 52 in which is disposed a quantity of print media in theform of business card sized paper or card sheets 54. These cards aresupported on a metal base plate 55 which is sprung by means of opposedspring fingers 56 as shown in FIG. 15. In this manner, the card supplyis constantly biased upwardly toward a media ejector mechanism 58. Theejector mechanism includes an ejector slider 59 which is operable uponmanual sliding against a return spring 60 to pick up the top card andfeed this out of the dispenser outlet 61 and into the media entry slot31 on the phone 1. On release, the slider automatically returns to thehome position to engage the next card ready for further loading.

Desirably, the printer phone 1 and/or printhead and ink supply module 16includes an authentication mechanism such as that outlined in theapplicant's earlier PCT application no. PCT/AU98/00544 entitled “Acamera with an internal printing system”. This can be used to ensure notonly that an authenticated approved consumable (such as the printheadand ink supply module) is used with the printer phone, but can also beused to store data on the relative usages of the consumable componentssuch as the ink or the printhead itself and can optionally be used toset a predetermined usage for these items.

As noted above; the phone device of the invention may be any kind ofmobile phone that sends and receives signals in a manner which can beprocessed into a printable form. Further, while the preferred formdescribed has a printhead and ink distribution unit which has anintegrally formed and attached ink supply, the ink supply could beseparate and optionally also separately replenishable.

While the invention has been described with reference to specificexamples, it will be appreciated by those skilled in the art that theinvention may be embodied in many other forms.
